Global Existence and Uniqueness of Weak Solutions of 3-D Euler Equations with Helical Symmetry in the Absence of Vorticity Stretching

Boris Ettinger, Edriss S. Titi

We prove uniqueness and existence of the weak solutions of Euler equations with helical symmetry, with initial vorticity in under "no vorticity stretching" geometric c…

Linear versus Non-linear Acquisition of Step-Functions

Boris Ettinger, Niv Sarig, Yosef Yomdin

We address in this paper the following two closely related problems: 1. How to represent functions with singularities (up to a prescribed accuracy) in a compact way? 2. How to reco…
